In the technique described in Patent Document 1, it is possible to shorten the time until the operation reorganization plan is applied to the actual operation by streamlining the confirmation process of the operation reorganization plan automatically generated by the computer. ..

However, since the generated operation reorganization plan is applied to the actual operation only by the user's approval operation, the operation status may change before the user performs the approval operation. As a result of changes in the actual operation status, if the target train included in the operation reorganization plan becomes "course controlled" or "arrival or departure at the designated station", the user determines that the operation reorganization plan cannot be applied. However, it may not be approved. In that case, the user has to perform the automatic generation request operation and the approval operation of the operation reorganization plan again, and there is a problem that it takes time to apply the operation reorganization plan to the actual operation.

The present invention has been made in view of the above problems, and an object of the present invention is to improve the possibility that the operation reorganization plan can be applied to actual operation by using predetermined conditions for determining the feasibility of the operation reorganization plan. The purpose is to provide an operation control support system and an operation control support method that can support the operation control work.

In order to solve the above problems, the operation reorganization support system according to the present invention is an operation reorganization support system that supports operation reorganization, and realizes an operation reorganization plan storage unit that acquires and stores the operation reorganization plan and a realization of the operation reorganization plan. Comparing the judgment condition storage unit that stores the predetermined conditions for determining the propriety, the operation reorganization plan acquired from the operation reorganization plan storage unit, and the predetermined conditions corresponding to the operation reorganization plan acquired from the judgment condition storage unit. However, it is provided with a determination unit that determines whether or not the operation reorganization plan satisfies a predetermined condition and outputs the determination result.

According to the present invention, it is possible to determine whether or not the operation reorganization plan satisfies a predetermined condition and output the determination result. Therefore, the user can use the determination result to determine whether or not the operation reorganization plan can be realized. Can be determined at an early stage, improving usability.

Hereinafter, the operation rearranging support system of the present embodiment will be described with reference to FIGS. 1 to 8. Further, in the present operation reorganization support system 1, an example in which the automatically generated operation reorganization plan becomes inapplicable depending on the actual operation situation will be described with reference to FIGS. 9 and 10. In this embodiment, the case where the operation control support system is applied to the railway operation system will be described as an example, but the present invention is not limited to this, and can be applied to the operation system of other mobile objects such as subways and monorails. is there.

FIG. 1 shows the system configuration of the operation control support system 1. The operation control support system 1 is configured as a computer system, and includes, for example, a central processing unit 10, a database 20, an input device 30, a display device 40, and a communication device 50. The configuration shown in FIG. 1 is an example, and the present embodiment is not limited to the system configuration shown in FIG. For example, one operation control support system 1 may be generated by linking a plurality of computers.

The central processing unit 10 includes a microprocessor and a memory (not shown). The microprocessor of the central processing unit 10 realizes predetermined functions 110 to 140 described later by executing a computer program stored in the memory.

The database 20 is provided on a storage medium such as a hard disk drive or a flash memory device, and stores each data 210 to 250 described later. The input device 30 is a device that receives input from the user of the operation control support system 1, and is configured as, for example, a keyboard, a mouse, a touch panel, a voice input device, and the like. The display device 40 is a device that provides information to the user. The display device 40 may include not only a display but also a printer, a speaker, a voice synthesizer, and the like. The display device 40 displays various GUIs (Graphical User Interfaces) including a diagram diagram. The communication device 50 is a device for connecting the operation control support system 1 and another computer system via the communication network CN.

Predetermined functions realized by the central processing unit 10 include, for example, an operation reorganization plan generation unit 110, a timetable diagram display unit 120, an operation status acquisition unit 130, and an operation reorganization plan applicability determination unit 140.

The operation reorganization plan generation unit 110 automatically generates an operation reorganization plan for recovering the disorder of the train schedule and registers it in the operation reorganization plan table 220. The timetable diagram display unit 120 generates a timetable diagram that graphically displays the train timetable and stores it in the operation timetable table 210. The operation status acquisition unit 130 acquires the train position, course, and actual time, and stores the train in the operation status table 240. The operation reorganization plan applicability determination unit 140, which is an example of the “judgment unit”, determines the applicability of the operation reorganization plan based on the acquired operation status.

The data managed by the database 20 will be described. The operation timetable table 210 stores the timetable data of the operation plan reflecting the traveled record in the operation timetable as planned. The operation reorganization plan table 220, which is an example of the “operation reorganization plan storage unit”, stores the operation reorganization plan generated by the operation reorganization plan generation unit 110. The station status information table 230 stores the equipment status and train presence information received from the station. The operation status table 240 extracts and stores the train position, course information, and actual time from the station status information table 230 and the operation schedule table 210. The timetable change content determination table 250, which is an example of the “determination condition storage unit”, stores the determination conditions of the operation status for applying the operation rearrangement plan to the actual operation.

FIG. 2 is a processing block diagram of the operation rearranging support system 1. When the operation reorganization support system 1 receives an instruction from the user to request the automatic generation of the operation reorganization plan, the operation reorganization support system 1 activates the operation reorganization plan generation unit 110. The operation reorganization plan generation unit 110 automatically generates an operation reorganization plan based on the timetable data stored in the operation timetable table 210, and saves the generated operation reorganization plan in the operation reorganization plan table 220.

FIG. 3 shows the table configuration of the operation timetable table 210. The operation schedule table 210 manages one train as one record. Each record includes, for example, a train number 211 and a station information unit 212.

The train number 211 is identification information for uniquely identifying the train. The station information unit 212 has items related to the name of the station on which the train runs and the arrival / departure time (arrival time and departure time).

The station information department manages information for one station (hereinafter referred to as station information) as one block, and stores the station information in the order of travel. Therefore, the first station information of the station information unit 212 is the information about the first station, and the last station information is the information about the last station.

As shown in the lower part of FIG. 3, the structure of station information is, for example, station name 2120, planned line 2121, planned time (arrival) 2122, planned time (departure) 2123, actual line 2124, actual time (arrival) 2125, Includes actual time (departure) 2126.

The station name 2120 is the name of the station. Plan number 2121 indicates the line used at the time of planning, the arrival time, and the departure time. The planned time (arrival) 2122 is the arrival time of the train in the operation plan. The planned time (departure) 2123 is the departure time of the train in the operation plan. The actual track number 2124 indicates the track used, the arrival time, and the departure time in the operation record. The actual time (arrival) 2125 is the arrival time of the train in the operation record. The actual time (departure) 2126 is the departure time of the train in the operation record.

FIG. 4 shows the table configuration of the operation reorganization plan table 220. The operation reorganization plan table 220 manages the timetable change information included in the operation reorganization plan automatically generated by the operation reorganization plan generation unit 110 of FIG. 2 as one record. Each record includes, for example, an operation reorganization plan ID 221 and a timetable change content 222, and a timetable change content detail 223. The operation reorganization plan ID 221 is information for identifying the operation reorganization plan. The timetable change content 222 indicates the type of timetable change information. Details of the timetable change 223 indicates attached information such as trains and stations subject to the timetable change. The operation reorganization plan ID 221 is numbered when the operation reorganization plan is generated. The timetable change information is stored in the order of generation.

Returning to FIG. 2, the description of the process is continued. After the operation reorganization plan generation unit 110 automatically generates the operation reorganization plan, the operation reorganization plan applicability determination unit 140 takes out the operation reorganization plan automatically generated from the operation reorganization plan table 220, and the operation reorganization plan is actually Determine if it is applicable to the operation of.

First, the operation reorganization plan applicability determination unit 140 acquires the operation status determination conditions for the operation reorganization plan from the timetable change content determination table 250. Next, the operation reorganization plan applicability determination unit 140 refers to the current operation status from the operation status table 240, and confirms whether or not the acquired determination condition is satisfied.

The operation status table 240 is created by the operation status acquisition unit 130 collecting the latest train information and actual information from the operation schedule table 210 and the station status information table 230 and storing them in the operation status table 1240. Since the operation status acquisition unit 130 operates periodically, the operation status table 240 is always in a state in which the latest operation status is stored.

FIG. 5 shows the table configuration of the timetable change content determination table 250. In the timetable change content determination table 250, check conditions for applying each timetable change to the actual operation status are defined in advance as static information. Each record includes, for example, a timetable change content 251 indicating the type of timetable change, a course check condition 252 which is a condition for determining applicability, and a performance check condition 253.

The timetable change content 251 includes a track change, a new train setting, a departure time change, and the like. The course check condition 252 is a condition relating to the course of the train. For example, the entrance course is uncontrolled and the departure course is uncontrolled. The performance check condition 253 is a condition related to the performance of operation, for example, there is no record of departure from a designated station.

FIG. 6 shows the table configuration of the station status information table 230. The station status information table 230 manages one station as one record. Each record includes, for example, items of source station name 231, basic information 232, interlocking display information 233, equipment status information 234, and on-line train information 235. Further, the on-line train information 235 can hold information on a plurality of trains on the target station. The information of one train has, for example, the items of the station on the line 2350 indicating the running position of the train, the train number 2351 indicating the unique ID of the train, and the route reservation information 2352 indicating the route control state of the train.

FIG. 7 shows the table configuration of the operation status table 240. The operation status table 240 manages one train as one record. Each record has, for example, a train number 241, a station name 242 on the line, a course reservation information 243, and an actual record information 244. The performance information 244 can hold the performance of a plurality of stations, and the performance of one station has the items of station name 2440, actual time (arrival) 2441, and actual time (departure) 2442.

The train number 241, the station name 242, and the route reservation information 243 store the train number 2351, the station 2350, and the route reservation information 2352 acquired from the station status information table 230 by the operation status acquisition unit 130, respectively. The station name 2440, the actual time (arrival) 2441, and the actual time (departure) 2442 of the actual information 244 are included in the station information of the train corresponding to the train number 241 acquired by the operation status acquisition unit 130 from the operation timetable 210. The station name 2120, the actual time (arrival) 2125, and the actual time (departure) 2126 are stored respectively.

FIG. 8 is a flowchart showing the processing in the operation reorganization plan applicability determination unit 140. Hereinafter, the operation reorganization plan applicability determination unit 140 may be abbreviated as the determination unit 140.

The determination unit 140 acquires all the timetable change information of the operation reorganization plan stored in the operation reorganization plan table 220 in order to determine whether or not the automatically generated operation reorganization plan is applicable (S10). The determination unit 140 repeats steps S12 to S16 by the number of records of the timetable change information acquired in step S10 (S11).

The determination unit 140 compares the timetable change content 222 included in the timetable change information to be processed with the timetable change content 251 of the timetable change content determination table 250, and acquires the course check condition 252 and the actual check condition 253 of the matching records. (S12).

If neither the course check condition nor the performance check condition can be acquired (S12: NO), the determination unit 140 does not need to determine whether the target timetable change information can be applied to the actual operation. Move to timetable change information.

On the other hand, when the determination unit 140 can acquire either the course check condition 252 or the performance check condition 253 of the matching record (S12: YES), the determination unit 140 moves to step S13.

The determination unit 140 acquires the train number and the designated station to be changed from the timetable change details 223 included in the timetable change information to be processed (S13). The determination unit 140 refers to the route reservation information 243 of the train number to be changed in the timetable acquired in step S13 from the operation status table 240, and the route control condition (entrance) defined in the route check condition 252 acquired in step S12. Alternatively, it is determined whether or not the departure course is uncontrolled, etc.) (S14).

When the determination unit 140 determines that the course check condition is satisfied (S14: YES), the determination unit 140 moves to step S16 and determines whether the performance check condition is satisfied. If the train number to be changed is not found in the operation status table 240 (trains on existing lines), or if the route check condition 252 does not need to be checked, the determination unit 140 unconditionally satisfies the route check condition. It is determined that the item is, and the process proceeds to step S16.

The judgment unit 140 refers to the actual information 244 of the train number to be changed from the operation status table 240, and the actual condition (actual time (arrival) or actual time (departure) of the designated station) defined in the actual check condition 253. (S16).

When the determination unit 140 determines that the performance check condition is satisfied (S16: YES), the determination unit 140 moves to the beginning of the loop and processes the next operation reorganization plan. If the train number to be changed is not found in the operation status table 240 (trains on existing lines), or if the performance check condition 253 does not need to be checked, the judgment unit 140 unconditionally satisfies the performance check condition. Judge as something.

If the condition is not satisfied in either step S14 or step S16 (S14: NO or S16: NO), the process proceeds to step S15. The determination unit 140 determines that the timetable change information to be processed cannot be applied to the actual operation, and stores the operation rearrangement plan ID 221 of the timetable change information that cannot be applied (S15).

The determination unit 140 moves to step S17 when the repetition for all the timetable change information acquired in step S10 is completed. The determination unit 140 confirms whether or not the operation rearrangement plan ID is stored in step S15 in order to determine whether or not there is timetable change information determined to be inapplicable (S17). If there is an operation reorganization plan ID determined to be inapplicable (S17: YES), the determination unit 140 moves to step S18.

The determination unit 140 notifies the operation reorganization plan generation unit 110 of the timetable change of the operation reorganization plan ID determined to be inapplicable, and requests the re-creation of the operation reorganization plan (S18).

Returning to FIG. 2, the description of the process is continued. When the operation reorganization plan applicability determination unit 140 determines that the automatically generated operation reorganization plan cannot be applied to the actual operation, the operation reorganization plan generation unit 110 is executed to regenerate the operation reorganization plan. On the other hand, when the operation reorganization plan applicability determination unit 140 determines that the automatically generated operation reorganization plan can be applied to the actual operation, the timetable display unit 120 is executed and the operation reorganization plan table 220 is displayed. The contents are displayed on the display device 40.

The operation reorganization plan applicability determination unit 140 may be executed not only after the operation of the operation reorganization plan generation unit 110, but also periodically. Even if the operation reorganization plan is once judged to be applicable by the judgment unit 140, it is possible to determine the applicability of the operation reorganization plan in more real time according to the actual operation situation by repeatedly determining the applicability. Become.

Here, the operation reorganization support system 1 of the present embodiment is not only for the operation reorganization plan determined to be inapplicable to the actual operation in step S18, but also for other operation reorganization plans determined to be inapplicable. The operation reorganization plan is also regenerated by the operation reorganization plan generation unit 110 (S18). In the example of FIG. 4, if it is determined that the operation reorganization plan ID "0020" and the timetable change content "track change" are not applicable, the operation reorganization plan (diamond) having the same operation reorganization plan ID "0020" The content of the change "time change") is also subject to regeneration. This is because the plurality of (two) operation reorganization plans are a set of reorganization plans having the same ID. Not limited to this example, for example, if there is a second operation reorganization plan premised on the realization of the first operation reorganization plan, or if it is determined that the first operation reorganization plan is not applicable, the second operation is performed. The rearrangement plan is also subject to regeneration. With the above processing, a series of flows in the present embodiment is completed.

Next, in this operation reorganization support system, an example in which the automatically generated operation reorganization plan is not applicable depending on the actual operation situation will be described with reference to FIGS. 9 and 10.

FIG. 9 shows an example of determining whether or not the operation reorganization plan is applicable based on the departure time. In FIG. 9A, the traffic light 310 indicates “stop” and the train 300 is stopped at the station. As a result of requesting the automatic generation of the operation reorganization plan in this state, it is assumed that the operation reorganization plan generation unit 110 has generated the operation reorganization plan for changing the departure time of the train 300.

After that, the operation status changed until the operation reorganization plan for changing the departure time was approved, the traffic light 310 changed to "progress" as shown in FIG. 9B, and the train 300 departed. Suppose you have. In this case, the operation reorganization support system 1 determines that the operation reorganization plan for changing the departure time cannot be applied because the actual time (departure) of the train 300 has already been set, and the operation reorganization plan is determined. Is regenerated by the operation rearrangement plan generation unit 110.

FIG. 10A shows a state before the train 300 passes through the point CP for controlling the entrance course. When the automatic generation of the operation reorganization plan is requested in this state, it is assumed that the operation reorganization plan generation unit 110 of the "track change" for changing the planned number of the train 300 from the number 330 to the number 320 is generated. ..

However, after that, the operation status changes until the operation reorganization plan is approved, and as shown in FIG. 10B, the train 300 passes through the point CP where the entrance course is controlled. For trains 300 that have passed point CP, the track can no longer be changed. Therefore, the operation reorganization support system 1 determines that the operation reorganization plan of "change of track", which has been waiting for approval, is not applicable because the entrance route 330 of the train 300 is in a controlled state, and operates. The rearrangement plan generation unit 110 regenerates the operation rearrangement plan.

According to this embodiment configured as described above, the following effects are obtained. In this embodiment, even if the operation status changes after the operation reorganization plan is generated, the suitability of the operation reorganization plan can be automatically determined, so that the user's operation reorganization work can be supported. Further, according to the present embodiment, even if the operation status changes after the operation reorganization plan is generated, the user does not need to perform the request operation for automatically generating the operation reorganization plan again. As a result, according to the present embodiment, the efficiency of the operation reorganization work can be improved, the speedy processing can be contributed, and the usability of the user is improved.

The present invention is not limited to the above-described embodiment. A person skilled in the art can make various additions and changes within the scope of the present invention. In the above-described embodiment, the configuration is not limited to the configuration example shown in the accompanying drawings. The configuration and processing method of the embodiment can be appropriately changed within the range of achieving the object of the present invention.
